- Ezh he L .1. will appear as the descripiion proce-feds, ille invention icsidcs in the combinnc: :nifl arrangement of parts and in im ilsaiils si sonsrruction hereinafter deniberland claimed, it being understood ze archange? in the precise embodiment of inznition herein lisciosedfcan be made within ibs scope of the following claims Without g from the spirit of the invention v.ng any of its advantages'.

parz @finis specil'ioationz-l"igure l is a A- 1 Munciein :.iccordsnce wih the present inr yloosely hrough perforations 18 1n guide vcntion; Fig. 2 is a horizontal sectionjnn the line of Fig. l; and Fi 3 is a 'v'er` ical section on the line 3 3 0 Fig. l..l

Like reference numerals indicate corresponding perfs in the diiercnt figures of the drawings. 'l The referrnce numeral l indicates a tank or c..` ig which may be of any suiiable ferm und cemsiruction. The casing 1 is suppl .fl willi' Water through an inlet pipe 2 :invii prc'rably is formed with exterior threads 3. The inlet. pipe 22 leads inl/J`I an inlel cbamber A. which preferably is circular in shape and consists of the wall el. kop l. and bottom 6. The. inlet pipe Q is threaded into lie bottom 6 nl The inlet chamber .L as shown. and a large Washer T preferably is inlerposed between flic bottom (i of the inic chamber il and the bottom ofthe casing .X .smaller washer 8 preferably is held against the lower side 'cf the bottoni 5G of :he casing l by means of a nui-'9 so as to farm u liquid-tight joint arolmflthe inlet pipe and other 'objects in ne acc-umbau in drawniifs formin'r;

esile-n through a flushing tank ccnf rub er ring J3, arelatively small annular plate ll, and a jam nut 15. The valve seat for each of the inlet valves B and C ref- .erably consists of a frusto-conicnl or ared portion 16 and a straight annular portion 17. lie portion i6 being adapted to receive Une rubber ring `13 and the ortion 17 being adapted to receive the smal annular plate 14: so that lsaid plafewill serve to receive the bulk of the liquid pressure, and the joint will be rendered tight by the rubber ring 13. The area of the straight annular portion 17 of each inlet valve seat is great-er than the area of the inlet ipe :2, the object of which is to provide allarge exit from the inlet chamber A so that the water may dow into Vthe 'casing l under a reduced pressure and without noise.

l For the purpose of guiding the `alves B andv C into proper contact. with their respective seats, the stems 10 are extended brackets 19 which are located within the inlet chamber A, the ends of said guide brackets being formed with flanges 2O secured to the top 5 by means of screws 2l. The fruide bracket 19 for the valve C is disposed a greater distance below the top 5 than the bracket. for the valve B, this construction being rendered necessary by the fact that the valve C moves downwardly into the inlet chamber A during its opening movement, While the valve B moves upwardly away from the chamber A and into the casing 1 during its opening movement. l

The means for movinv the valves B. and C simultaneously in opposite directions lo close or open the inlet chamber A so as to permit the water contained therein to How into the casing 1, preferably consists of In' operating lever D which is pivotally mount'- ed at 22 upon n siandard 23 having its lower "end reduced in diameter and extended The means for controlling the flow of? wafer `imm the inlet chamber A to thei through tire t 5 of the inlet chamber A, said standard ing held in position by a nur, 24 bearing against the lower surface of the top 5 of the inlet chamber. 'Ble opent- AIl() -to move vertically in `the casing l and is to flow from the inlet chamber A into the -canse said lever to open the valves B and C l metallic strips 'BTP-"25v which, adjacent the standard are bent into parallelism with l each otl'ieinnd tit against opposite sides of said standard, said strips being spaced apart by means ot' spacing sleeves 'en through which extend the attaching liolts 27. lach of the valve stems l@ of the valves B :ind C at its upper end extends between the nielsili lic strips 25 and is pivotzilly connected therei with as indicated at 2S. lt. will be observed that the pivot point of the operating lever D is disposed intermediate the pivot points 28 of the valves llv :ind C, so that ns seid operating lever is moved in one direction or the other, the valves B :1nd C are simultaneonsl: moved in opposite directions. Adjacent the pivot point 2S of the valve C, the metallic strips 25-525 of the operating lever are bent so as to diverge with respect to each other, as indicated ut 29, und are then bent into parallelism with each other, as indicated at 30, the parallel ends 30 beit-gg spaced away from eneli other, as shown, for :i purpose which will presently appear.

T he means for rocking the operating lever D when the easing l becomes empty so es to and thus permit the casing 1 to be refilled from the inlet chamber A and pipe 2,V preferably consists of a float, E which is adapted guided in its vertical movements by means of sleeves 31 'which me secured to said Hout and slidnbly embrace vertically extendin'v guide rods 3'?. which preferably are mounted at.- their upper und lower ends in bracket members 33 suitably disposed in the easing 1. The doet li nrefernbly is provided with n false bottom 36e through which extends n l st nd 35 having a flared upper end 3G-zand being' held in place hy a transverse pin 3T. T he stud 35 at its lower f :nd is slotted, so :is loosely to receive the pivot pin 89 of :in :um 40 which is eorqiectcll with n cross-piece ell extending between the spaced pnmllel ends- 30 of the operating lever D. lt will be ol)- vions that as the water is withdrawn from the easing l, the float E will descend by ravity nml by pressingr downward upon the ong end of the operating lever D will move' the vsilves B und C in opposite directions' thus causing said valves to permit water casing 1 until the float E rises to its highest `ition und causes said -vulves to be closed. or the purpose of regulating the depth of vater in the casing 1, the pivot in 39 of the i arm 40 is made readily remove le and said nur-l0 is threaded'. as indicated at 42, so that by removing the pivot pin -izmd rol ating the arm 40 said arm can be adjusted with respect to the cross-piece 41 to regulate l :the distance-between tno lever D and the bottorof the float E, whereby slid Boat cm is operated, ho'fmver,t the. outlet valve is l casing l. The bushing el irri.-

Condition. s i-liewater gradually rises around the outlet valve. the pressure of the Water holds mid valve .warmly nennst the bushing: 44. even against x'l-e fendeiwy of the vulve to rise on :accenni of (ne tmoynin'y of the nous 61 and 6:2'. fl-lim the cord 3.9

i ing 44 to he out of th influente of the sucwater level never falls as low as the inlet 4lVliy the Water level always remains above stein 5l. the outlet valve will not oontact .ends (i7 of which :ire disposed at the desired vom 1 moved sufficiently far away from the bushtion or pressure of the water and the floats 61 and (i2 will consequently cause the outlet valve to float until the proper amount of water has drained out of the tank. The

chamber A the latter therefore is always submerged and water llovving therefrom cnters a body of water in the casing 1 which, in connection v-'ith the reduced pressure of the incoming Water, prevents any noise.

the inlet chamber A is made plain when it is remembered that the quantity of water flowing ont of the tank, when the outlet valve is opened, is governed by the float 6l which descends as the' Water level lowers until said outlet valve is seated; and as said float is fastened to the valve stein above, theinlet chamber A, it naturally follows that the level of the Water in the casing l can never fail lower than the float. As soon :is the Water begins to drain out the float E descends so as to open the inlet valves B and C and thus permit a quantity of Water to enter Athe tana even vvnile the throu the outlet pipe 43. It will be observ. that the upper end of the bushing 44 extends above the bottom of the casing 1, for which reason the overflow pi es 66 can be conducted into said bushing Without por- '70 forating the bottom of the casing l, or conducting the pipes F315 outside of said casing.

The improved flushing tank of this invention is strong, simple, durable and inex pensive in construction as well as thor.-

tending through the bottom of the tank and provided with a valve seat, a valve enga lng eaid seat, a stem extending vertically grom the valve, a hollow conical casing surrounding the valve, stem and resting on said valve,

a vertically adjustable float slidably mounted on the valve stern above the conical casing, and an operating lever ivotally connected with the upper end of tile valve Stem.

2. The combination with a -flushinglank including an inlet valve, an outlet pipe extending through the bottom of the tank and provided with a valve wat, a supportin outlet valve is open. For the purpose of -t'ranie extending above the valve seat an regulatingthe amount of water which is to be permitted to foiv from the casing 1, the float 6l is adapted to be adjusted vertically upon the stein 51 of the outlet valve. This vertical adjustment preferably is secured by mcuns of a .set screw 83 which extends through a sleeve 64 on the up r end of the porting frame and slidably mounted on .said

float (il and impinges against t .e stem 5l. ln

provided with verticallyr alined openings, a

valve rengaging said seat, a stem secured to valve stem, means for locking the fioat in.

order to render the float 6l air-tight, said adjusted position, and an 'operating lever float is formed with an inner tube 65 which surroundsthe .stem Lasshown. If the float 6l he adiusted bidh upon .the stem 51, the outlet. valve will escend against the bushing 44 after a comparatively small quantity of water has escaped from the casing l; and if the tloat. 61 be adjusted low upon the with the bushing 44 until a comparatively pivotally mounted on the supporting frame and o rativelv connected with the upper end o the valve 3. Ine eonibination with a flushing tank includingean inlet valve, a valve seat secured to thv` bottoni of the tank and provided with interior threads, an outlet pipe engaging the thre'adsof the valve seat, a valve resting on 110 said seat, a supportinf frame having vertilarge quantity of water has esca d from cally alined openings ormed therein, astein secured to the valve and slidably mounted in said openings, a hollow conical casing resting on the valve, an adjustable tlf-at ls- 115 poseo" ahoveetlie conical casing and having a sleeve for the reception of the valve sten:i
